( Figs. 19 F-G, 35E)

Physodactylus fischeri Fleutiaux, 1940c: 166 ; Blackwelder, 1944: 292.

Redescription (male, Fig. 35E ): Integument bright, head with frons black, gradually lighter posteriorly with the same color of pronotum at base, prothorax reddish-brown, antenna, elytra and ventral abdomen black, ventral pterothorax and legs dark brown; pilosity brown. Total length 17.0 mm; elytral base 1.03x as wide as prothorax, elytra 2.98x longer than pronotum. Frons slightly concave, frontal carina not produced; antenna reaching the half length of pronotum; antennomere IV 1.05x as wide as long, V-VII 1.20x wider than long; VIII-X 1.0-1.1x as wide as long; XI oval 1.28x longer than wide. Pronotum 1.28x wider than long, lateral sides rounded convergent from posterior angles to anterior margin; anteromedian margin weakly produced; posterior angles short, convex, parallel; lateral carina dorsally visible only on posterior third, absent on anterior half; disc with punctures 2-3 diameters apart, larger and denser on lateral and anterior borders. Lamellae of pro- and mesotarsomeres I smaller than the others, absent or minuscule on metatarsomere I. Elytra subparallel on anterior 2/3 then tapering to apex; striae with large and small dense punctation, indistinct on apical region where the punctation is mixed; interstices convex and rugose, scarcely punctate; apical striae with punctures larger than those of pronotal lateral border. Abdomen with ventrites 2-4 concave laterally, 1-4 evenly covered with decumbent, moderately long pilosity, setae of ventrite 1 as long as those of ventrite 2. Pregenitalic segments and aedeagus covered with stout dark-brown setae. Sternite VIII with posteromedian margin emarginate, anterior sclerotization 0.28x the total width of sternite; sternite IX with apex rounded.

Aedeagus ( Figs. 19F, G ): Phallobase 0.52x the total length of aedeagus, 1.27x longer than wide, length ratio between lateroposterior and median parts 11.5; paramere with ventral surface partly sclerotized, anteromedian margin with a long median sclerotized strip convergent anteriad; penis with basal strut 0.27x its total length, articulated to the parameres by a translucent membrane; ventral sclerite linear.

Holotype: [Bahia, Brasil], [TYPE], [ Physodactylus fischeri Fleut. , COLLECTION FLEUTIAUX type], [Muséum Paris, Collection E. Fleutiaux], [LECTOTYPE], [ Physodactylus fischeri Fleut., J. Chassain det. 05], male (MNHN).

Distribution: BRAZIL. Bahia.

Remarks: The apex of the prosternal process was not examined. Physodactylus fischeri is recognized by the following combination of characters: antennae reaching the posterior half of pronotum, lateral pronotal carina absent on anterior half, elytral striae densely punctate and indistinct on apical region and pilosity of the ventrites 1-4 subequal.
